Abstract
In every century of history, there are many new diseases emerged, which are not even cured by many developed countries. Today, despite of scientific development, new deadly pandemic diseases are caused by microorganisms. Hygiene is considered to be one of the best methods of avoiding such communicable diseases, especially viral diseases. Illness caused by SARS-CoV-2 was termed COVID-19 by the WHO, the acronym derived from "coronavirus disease 2019. The globe is living in the worst epidemic era, with the highest infection and mortality rate owing to COVID-19 reaching 6.89% (data up to March 2023). In recent years, nano biotechnology has become a promising and visible field of nanotechnology. Interestingly, nanotechnology is being used to cure many ailments and it has revolutionized many aspects of our lives. Several COVID-19 diagnostic approaches based on nanomaterial have been developed. The various metal NPs, it is highly anticipated that could be viable and economical alternatives for treating drug resistant in many deadly pandemic diseases in near future. This review focuses on an overview of nanotechnology's increasing involvement in the diagnosis, prevention, and therapy of COVID-19, also this review provides readers with an awareness and knowledge of importance of hygiene.

Abstract
The use of plant extracts is a low-cost and green way to synthesize nanoparticles. In this research, the authors investigated the antibacterial, cytotoxic and antiangiogenic properties of silver nanoparticles (AgNPs) synthesized using Amaranthus cruentus extract. The fabricated nanoparticles were characterized by transmission electron microscopy (TEM), field-emission scanning electron microscopy, Fourier transform infrared spectroscopy, dynamic light scattering and X-ray diffraction. The TEM results showed that the typical size of the AgNPs recorded was 15 nm. Biological tests indicated that the biosynthesized AgNPs had caused a decrease in cancerous cells (MCF-7) and had a high antibacterial activity against Escherichia coli, Staphylococcus epidermidis and Staphylococcus aureus. According to data analysis, the number and length of the blood vessels in different concentrations of AgNPs reduced significantly (depending on the dose). The chorioallantoic membrane assay revealed a large decrease in the number and length of angiogenic blood vessels in the presence of AgNPs. Real-time polymerase chain reaction and flow cytometry studies showed a dramatic increase in the gene expression of caspase-3 and caspase-8.
